Plan of Conservation and Development
“As a prerequisite for all planning and analysis as part of the Plan of Conservation and Development Update, a digital base map was prepared in order to use Geographic Information System (GIS) technology. The digital file to create the base map as well as a link to data on a parcel basis contained in the Assessor’s records was provided by the Milford Management Information Systems Department.” Page 2, City of Milford, CT Plan of Conservation and Development
